Good afternoon, winter weather weenies. The pattern continues to head into the extreme as we roll toward late Sunday into early next week. A dangerous blast of arctic air will dive in here Sunday night and will be preceded by a nasty band of snow.

I really don’t have very many changes to my overall thoughts on how this all plays out. As always, a few issues will have to be cleaned up as we get closer. Let’s break it down…

– As I’ve been saying for a few days… this isn’t about the track of the low pressure. It’s all about the band of heavy snow that swings in behind the arctic front.

– Temps today or ahead of the arctic front have no real influence on what happens BEHIND the front.

– The front will be pushing across western Kentucky Sunday morning and won’t reach the east until the evening hours. Accumulating snow for most areas won’t take place until late in the afternoon into Sunday night. Don’t freak out when the sun is out and it’s in the 40s in front of the front. 🙂

– This snow band will be on the nose of the arctic air diving in from the northwest. There looks to be plenty of lift to get the snows to crank up. Gusty winds of 40mph will blow the snow around and may create whiteout conditions at times.

– This still looks like a general 1″-4″ across the state. Higher amounts will be possible in the far west and far north near Covington. I can also see some higher totals along the Virginia border counties. I made a new call for snowfall map and just realized I saved over it and I’m too lazy to go back and redo it. 🙂 How’s that for honesty?

– Temps will CRASH from west to east behind the front. With the wet roads from showers ahead of the front… a flash freeze of roads will be likely. Throw snow on top of that and significant travel problems will be likely Sunday evening and night. This is another HIGH IMPACT travel event.

– Temps drop below zero by Monday morning and likely stay there through the day and into Tuesday morning…

GFS

– Those numbers are BRUTAL and record lows are in jeopardy for both Monday and Tuesday. Wind chills will make this an even more dangerous situation than what it already is. Wind chill numbers of -30 will be possible Monday and Tuesday. Those types of wind chills are RARE here and have only occurred on a limited number of occasions in the modern era of record keeping.

– RESPECT THE COLD! Take all necessary precautions to protect life and property before the blast arrives.

– Longer range… an overrunning snow and ice system is very possible by Thursday. Winter takes about a 5-7 day break after that, but it comes roaring back after that. I don’t think this is the last time the Polar Vortex impacts our weather.

I will have more updates later in the day and will have a final call for snowfall later tonight. Again… most of your snow won’t arrive until late Sunday into Sunday night.

Enjoy the rest of the day and take care.
